把mysql資料庫產生資料字典，直接可用便於查看資料庫表、欄位，做一個資料字典是很有必要的。本文主要為大家詳細介紹了php產生mysql的資料字典的相關資料，感興趣的小夥伴們可以參考一下。希望對大家有所協助。

下面的代碼只需要簡單更改下配置就可以用了，樣式也是挺好的。

<?php header('content-type:text/html;charset=utf-8'); define('DB_HOST','localhost'); define('DB_USER','root'); define('DB_PASS','root'); define('DB_NAME','test'); define('DB_PORT',3306); define('DB_CHAR','utf8'); define('APPNAME',''); $conn=mysql_connect(DB_HOST.':'.DB_PORT,DB_USER,DB_PASS); mysql_select_db(DB_NAME); mysql_query('set names ' . DB_CHAR); $sql="SHOW TABLE STATUS FROM " . DB_NAME; $result=mysql_query($sql); $array=array(); while($rows=mysql_fetch_assoc($result)){ $array[]=$rows; } // table count $tab_count = count($array); echo '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="zh"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>'.APPNAME.'--資料字典</title> <style type="text/css">   table caption, table th, table td {     padding: 0.1em 0.5em 0.1em 0.5em;     margin: 0.1em;     vertical-align: top;   }   th {     font-weight: bold;     color: black;     background: #D3DCE3;   }   table tr.odd th, .odd {     background: #E5E5E5;   }   table tr.even th, .even {     background: #f3f3f3;   }   .db_table{     border-top:1px solid #333;   }   .title{font-weight:bold;} </style> </head> <body> <p style="text-align:center;background:#D3DCE3;font-size:19px;">   <b>'.APPNAME.'--資料字典</b> </p> <p style="background:#f3f3f3;text-align:center;">（註：共'.$tab_count.'張表，按ctrl+F尋找關鍵字）</p>'."\n"; for($i=0;$i<$tab_count;$i++){ echo '<ul type="square">'."\n"; echo ' <li class="title">'; echo ($i+1).'、表名：[' . $array[$i]['Name'] .
